Problems solved by technology

Phosphorus-nitrogen flame retardants can meet environmental protection indicators, but if they want to achieve the ideal flame retardant effect, they need to be added in a large amount, which will cause poor mixing and dispersion of resins, flame retardants, and other fillers, and poor compatibilizers. indicators drop
Moreover, its dimensional stability is very poor, and there will be gaps between the floors under thermal expansion and contraction.

preparation example Construction

[0078] The preparation raw material of the second base material layer in the present invention is the same as that of the first base material layer, except that there is no glass fiber in the filler of the second base material layer and the content is less, and the lubricant in the auxiliary agent is different.

[0079] In one embodiment, when the preparation raw materials of the first substrate layer include 10% resin, 5% toughening agent, 5% compatibilizer, 5% wood flour, 25% flame retardant, 0.7% additive , the balance is filler, the preparation raw material of described second substrate comprises 15% resin, 10% toughening agent, 10% compatibilizer, 10% wood powder, 20% flame retardant, 0.72% auxiliary agent, balance For the filler.

[0080] In another embodiment, the raw materials for preparing the second substrate include 22% resin, 8% toughening agent, 5% compatibilizer, 15% wood flour, 20% flame retardant, 0.72% additive, The balance is filler.

[0081] In another emb...

Embodiment 1

[0139] Embodiment 1 of the present invention provides a wood-plastic floor, which is a substrate layer, a connecting layer, and a wear-resistant decorative layer from bottom to top; the substrate layer includes a first substrate layer and a second substrate layer from top to bottom. Substrate layer; The wear-resistant decorative layer includes a wear-resistant protective layer and a printed decorative layer from top to bottom; The wear-resistant protective layer includes a wear-resistant UV coating layer and a transparent protective layer from top to bottom; The printed decorative layer Including ink layer and printing substrate layer from top to bottom.

[0140] The raw materials for the first substrate layer include 10% resin, 5% toughening agent, 5% compatibilizer, 5% wood powder, 25% flame retardant, 0.7% auxiliary agent, and the balance is filler.

[0141] The resin is PP, purchased from Formosa Plastics Polypropylene 3005.

[0142] The toughening agent is EMA, purchased...

Embodiment 2

[0173] Example 2 of the present invention provides a wood-plastic floor, the specific implementation of which is the same as in Example 1, the difference is that the preparation raw materials of the second base material are 22% resin, 8% toughening agent, 5% phase Compatibilizer, 15% wood powder, 20% flame retardant, 0.72% auxiliary agent, and the balance is filler; the compatibilizer is MAH-EBA, purchased from DuPont coupling agent Fusabond A560 in the United States.

Abstract

The invention relates to the technical field of plastic board preparation, and more specifically, the invention provides a wood-plastic floor and a preparation method thereof. The first aspect of the present invention provides a wood-plastic floor, which is a substrate layer, a connecting layer, and a wear-resistant decorative layer from bottom to top; the substrate layer includes a first substrate layer and a second substrate from top to bottom layer; the wear-resistant decorative layer includes a wear-resistant protective layer and a printed decorative layer from top to bottom; the wear-resistant protective layer includes a wear-resistant UV coating layer and a transparent protective layer from top to bottom; the printed decorative layer is from top to bottom Including the ink layer and the printing substrate layer.

Description

technical field [0001] The invention relates to the technical field of wood-plastic floor preparation, and more specifically, the invention provides a wood-plastic floor and a preparation method thereof. Background technique [0002] Wood flooring has always been an ideal ground decoration material in people's minds, and it is strong and durable. However, with the improvement of people's quality of life, it is found that the wooden floor is not moisture-proof, and there will be gaps between the floors after long-term use, which will make noise, and at the same time cause a large number of trees to be felled, destroying the ecological balance. As a result, wood-plastic flooring has sprung up like mushrooms after rain. [0003] Wood-plastic flooring is a composite material that consists of cheap wood flour and polymer resins. Its development has made great contributions to the protection of forest resources and the ecological environment, making full use of recycled waste pl...
